An effect of Reclaimed Asphalt Concrete on the Strength Development of Concrete using Recycled-Aggregate

폐아스콘을 함유한 재생콘크리트의 강도발현 특성평가

The purpose of this study is to recycle waste concrete and reuse reclaimed asphalt concrete as a concrete coarse aggregate. In this experiment, recycled coarse aggregate was substitute for natural crushed aggregate at the rate of 0, 30, $50\%$, and reclaimed asphalt concrete was substitute for recycled coarse aggregate at the rate of 0, 10, 20, $30\%$. According to the experimental results, as the reclaimed asphalt concrete content has influence on the properties of recycled aggregate concrete such as compressive and tensile strength, the criteria for the substitute ratio should be required to be set.
